AWS S3 contd

• Only Empty Buckets can be deleted
  

Storage classes in S3

• Create an s3 bucket and upload some objects
  
  
  

Lets find destinations in s3 uri formats

• S3 URI Format:
  • bucket: s3://<bucket-name>
  • folder: s3://<bucket-name>/<folder-name>
  • object: s3://<bucket-name>/<object-name> or s3://<bucket-name>/<folder-name>/<object-name>

Lets find the ARN (Amazon Resource Name)

• ARN uniquely identifies the resources created in AWS
• ARN for s3 Refer Here

arn:aws:s3:::bucket_name/key_name

• ARN for my bucket qtstorageclassdemo will be arn:aws:s3:::qtstorageclassdemo
• ARN for my object one.mp3 will be arn:aws:s3:::qtstorageclassdemo/music/one.mp3

Bucket Properties

• Navigate to s3 console and select the bucket and click on properties
  
• Location/Region
• Bucket versioning
• Tags
• Default Encryption
• Transfer Accelartion
• Requester Pays
• Static Website Hosting

Versioning

• By default if we upload the object with sme name it overrites, when we enable versioning a new version of the object with same name is created and this becomes the default version
• Enable versioning
  
  
• upload 2 versions of some text file
  
  
• Now suspend versioning i.e. from now on no more versioning.
• As of now one.txt has two versions
  
• lets add one more one.txt

Requester pays

• In S3 we have two costs
  • one for storage
  • other for access
• Requester pays is a mode where the user should be aws user from other account who will be paying access cost and you would only be paying storage costs.
